EP on the Columbia label from 1962. Accompaniment directed by Brian Fahey. Pinky & Perky were a popular puppet duo on children's television who did versions of many of the pop songs of the day. I suppose the American equivalent would be The Chipmunks.

"The title characters are a pair of anthropomorphic puppet pigs created by Czechoslovakian immigrants Jan and Vlasta Dalibor. The puppets, who had only very limited movements, looked very alike. Pinky wore red clothes and Perky blue, but this distinction was little use on black and white TV, so Perky often wore a hat. Pinky and Perky spoke and sang in high-pitched voices created by re-playing original voice recordings at twice the original recorded speed; the vocals were sung by Mike Sammes while the backing track was played at half normal speed (Sammes did the same job for Ken Dodd's Diddymen, as Ross Bagdasarian did for the original Chipmunks in the early 1960s) - hence the expression "Pinky and Perky speed", when an LP record is played at 45 rpm or 78 rpm instead of the correct 33⅓ rpm. Pinky and Perky would often sing cover versions of popular songs, but also had their own theme song "We Belong Together." They had their own TV station "PPC TV". They also performed comedy sketches usually with a human foil (similar to Basil Brush). Actor John Slater worked with them as a straight man for many years, enduring soakings from water pistols and such pranks. Other human companions included Roger Moffat, Jimmy Thompson, Bryan Burdon and Fred Emney. Their show included other puppets, such as The Beakles (an avian parody of The Beatles), Topo Gigio, a famous mouse puppet who appeared in many later episodes, as well as a female pig. Other puppets included Ambrose Cat, Basil Bloodhound, Bertie Bonkers the baby elephant, Conchita the Cow, Horace Hare and Vera Vixen."
